A breif way of Notation.XVI. From the rules aforegoing, an eaſie way may be collected to read or expreſs the value of a Number propounded, Viz. Let it be re-quired to read or pronounce this number 521426341, Firſt, Diſtinguiſh by a Comma, or point, ever three places, beginning at the right hand, and proceeding towards the left, ſo will the aforeſaid number be diſtinguiſhed into parts, which may be called A period.Periods, and ſtand thus 521,426,341. where you may note the firſt period towards the right hand to conſiſt of theſe figures 341, the ſecond of theſe 426. and the third of theſe 521. Secondly, read or pronounce the figures in every Period as if they were ſtood apart form the reſt, ſo will the firſt Period be pronounced three hundred forty one, the ſecond four hundred twenty ſix: and the third five hundred twenty one. Thirdly, to every Period except the firſt towards the right hand, a peculariar denomination or ſirname is to be applyed, Viz. the ſirname of the ſecond Period is Thouſands; of the third, Millions; of the fourth, Thouſands of Millions, &c. Therefore beginning to pronounce at the higheſt Period, which in this Example is the third, and giving every Period its due ſirname, the ſaid number will be pronounced thus, Five hundred twenty one Millions, four hundred twenty ſix Thouſands, three hundred forty one.

Note, When a number is diſtinguiſhed into Periods, as before, the higheſt Period will not always compleatly conſiſt of three places, but ſometimes of one place, and ſometimes of two, nevertheleſs after ſuch Period is pronounced as if as if it ſtood apart, the due ſirname is to be annexed; ſo this
